need help with codes - 2006 GX470 (1 Viewer)

[StrongIslandGX]

Hi all, I just bought a 2006 GX470 (200k miles) about a month ago and today the CEL, VSC TRAC, VSC OFF, and Traction Control lights all came on. I plugged in a code reader and the following codes came up:
C1201 - Engine Control System Malfunction
C1223 - Malfunction in antilock Brake System Control system
C1241 - Low Battery Positive Voltage or Abnormally High Battery Positive Voltage
C1253 - Hydro-Booster Pump Motor Relay Malfunction
P0420 - Catalyst System Efficiency Below Threshold Bank 1

the code reader classified the C-codes as ABS codes?

My Google-fu did not come up with any solid direction to trouble shoot, with things being said about bad battery, low brake pads, O2 sensors, bad cats, and even gas cap. I'm so confused. Anybody here experience this specific combination of codes? Can anyone help shed some light into what I am up against?

Thanks, and happy to join this group!

so I'm guessing this is a little more than just a new gas cap to fix? Lol, bumping this up to see if I can get some help, thanks in advance.

Low battery voltage can cause all those codes. Make sure you battery and alternator are good before you do anything else. I’ve had similar issue caused by a battery!

OK thanks for the input! I am due a new battery and fluid maintenance soon, so I will see what happens afterwards before I spend more money trying to throw parts at it. Thanks!!

OP, Just wondering if you were able to resolve these codes with new battery. I am getting the same list of codes too.
